WALTER w. wrcx, or SHEBOYGAN, Wisconsin,

MACHINE FOB MECHANICAL WASHING AND STERILIZING OF THE HANDS.

Application filed July 6, 1920.

To all whom it may concern:

Be it known that I, WALTER W. WIGK, a citizen of the United States,residing at Sheboygan, in the county of Sheboygan and State ofWisconsin, have invented certain new .and useful Improvements inMachines for Mechanical Washing and sterilizing of the Hands, of whichthe following is a speclfication.

This invention relates to 'd vices for cleansing and sterilizinghandsgand the like, and, while especiallyadapte for use in hospitals,manufacturing establishments and the like, where a large number ofpeople are employed, is not limited in its scope or utility, to suchuse.

An object of the invention is to provide a device permanently fixed anddriven by a motor having means for applying abrading or disinfectingmaterial or detergents, together with water for cleansing andsterilizing the hands and arms.

Another object of the invention is to provide a bowl rotating within ahousing within which the cleansing liquid is contained, said bowl havingmeans for throwing and splashing the cleansing liquid upon the hands.

With these and other objects in view, the device comprises certain novelelements, units, constructions, parts, combinations and functions aswill be hereinafter more fully described and claimed.

In the drawin Figure 1 is a view of the device in vertical diametricalsection.

Fig. 2. is a vertical diametrical section taken at right angles to theplane of Fig. 1, as indicated by line 22 in said figure.

Fig. 3 is a top plan view with the motor omitted.

Fig. 4 is a view of the bowl in side elevation.

Fig. 5 is a view of theouter brush removed.

Fig. 6 is a view in side elevation of a modified type of the device.

Fig. 7 is'a top plan view of the modified ty e.

Fig. 8 is a horizontal sectional view, showin the gear drive of themodified type.

ike characters of reference indicate corresponding parts throughout theseveral views.

Specification of Letters Patent.

Serial No. 394,272.

comprises a housing 10 supported in any approved manner, as by a bracket11, capable of belng secured to a wall or other stationary objectindicated at 12. The hous ,Within the housing 10 a spindle 16 isjournaled having a gear 17 co-acting with the gear 18 carried 'upon theshaft 14 whereby the gear 17 and spindle 16 are driven.

Upon the spindle 16 above the gear 17 a bowl 19 is secured in anyapproved manner, as by applying a nut 20 to the spindle clampmg the bowlrigidly against the gear 17. The bowl'may also be provided with amult1angular neck 21 which may fit a socket complementarily proportionedin the gear 17.

The housing 10 is provided with a top member 22 of hopper formationhaving an lnwardly downwardly turned lip as at 22', whereby the openingof the bowl is somewhat constricted. The bowl is provided with aplurality of perforations 23 and with wings or vanes 24 spaced about theperiphery of such bowl, preferably between the openings 23.

At one side the housing is provided with an offset chamber 25 having aclosure 26 and I adapted to contain detergent or antiseptic screwed downupon the nut 20. An outer brush 32 is prefarably formed with a springback whereby it may be contracted from the form shown at Fig. 5 orstraight as may be to nearly a complete circle to fit within the upperportion 0 the bowl 19 and by its own resiliency and the centrifugalforce of the rotatin bowl be retained in such position.

In t e type shown at Figs. 1 to 5, inclusive, the detergents orantiseptics are placed in the chamber 25 and water admitted through thepipe 27 to such level as to come into engagement with the materials inthe chamber 25 through the perforations 33. The valve 29 being closed toretain the water in the housing 10, the motor is start-- .tated by thevanes 24 to ed, rotating the bowl 19 with great velocity, whereby thewater in the housing is agiterials in the chamber 25 and to throw itupwardly against the lip 22 deflected to the interior of the bowl andinto engagement withthe hands inserted between the brushes 30 and 32escaping through the perforations 23.

The, type shown at Figs. 6 t0-8, inclusive, comprises a housing 34cylindrical throughout the major portion of its length wlth ahopper-like constriction 35 at the top similar to the top 22 of thepreferred embodiment.

. Within the cylindrical housing 34 a plurality of vertical spindles 36are journaled having brushes 37 thereon and provided with gears 38. The37 carried thereby are driven-in any approved manner, as by a centralgear 39 meshing with agear 40 upon the motor arbor 14. The necessarywebs 41 and 42 to provide bearings for the spindle 36 are preferablycast integral with the housing 34 with the gears 38, 39 and 40 locatedbetween such webs. It is obvious that the integrality of the webs andthe housing is purely a matter-of choice, and any other manner ofconstructing will equally as well servethe purpose.

A chamber 43'similar to the chamber 25 is provided for the same purposeand the operation and function are the same, it

belng apparent that the interval between dissolve the ma by which it isgears 38 and the brushes the brushes is greater in this type than in thepreferred form,

as well as the hands, to be operated upon.

claim:

1. A device for cleansing hands and the like comprising'a bowl having aconstricted opening in the top embodying an inwardly downwardly directedlip, brushes,

mounted to rotate in the bowl under the lip and means'to supply acleansingliquid in the bottom of the device stopping short of the topsof the brushes.

2. A device for cleansing hands and the like comprising a bowl having aconstricted opening in the-top embodying an inwardly downwardly directedlip, means to admit cleansing .liquidto the bowl to partially fill thesame, and brushes and'brush carriers journaled to rotate partly in andpartly out of the, liquid and to splash liq-.

uid upwardly into engagement with the lip.

3. A device for cleansing hands and the like comprising a housing, abowl mounted to rotate within the housing, and provided with peripheralperforations, means to control a cleansing liquid within the housing tomaintain a level lower than the perforapermitting the forearm,

tions,- a downwardly inwardly directed lip c arriedby the housing andoverhanging the bowl and means upon the exterior of the bowl to splashliquid upwardly to be deflected by the lip downwardly into the bowl. 1
